Topic Modelling (TM) has gained momentum over the last few years within the humanities to
analyze topics represented in large volumes of full text. This paper proposes an experiment …

Passive techniques such as barriers, silencers and isolation are bulky, costly and ineffective
at low frequencies. Active cancellation of noise was presented because of these problems …

BACKGROUND In audio listening applications, it is normally desirable to minimize the
amount of background noise heard by the user. Methods for achieving such reduction fall …

This paper presents a hearing device with an adaptive noise canceller for noise-robust voice
input. The hearing device has an inner-ear and an outer-ear microphone to collect ear-canal …

Active noise control (ANC) is based on the destructive interference between the primary
noise and generated noise from the secondary source. An antinoise signal with equal …

Active noise control (ANC) is a method used to reduce acoustical vibrations mainly within
the low-frequency range. This thesis aims to implement a wireless active noise control …

本研究針對傳統回授式FXLMS 演算法來改善噪音干擾時減噪量不足的情形,
提出在管路減噪系統中, 將FXLMS 演算法搭配運用Haar 小波函數轉換與低通濾波器 …

In this paper, we propose a method that can be applied to the efficient implementation of
multi-channel active noise controller. Since the normalized MFxLMS (Modified Filtered-x …

Passive methods such as silencers and isolation are large, costly and ineffective at low
frequencies. Active cancellation of noise was presented because of these problems. In this …

The design and development of a duct based experimental setup has been presented to
investigate the active noise cancellation of narrowband as well as broadband scenario. The …
